Abstract:

In order to design an efficient sensor network, localization of nodes is an important aspect. Nodes present in the sensor network need to send and receive data in order to carry out the communication. For the communication to be carried out in an effective manner each and every node should be aware of the location of all the nodes present in the sensor network. Various localization schemes has been devised. In this paper, the comparative analysis of range free localization techniques are studied, discussing about its basic terminology and how the future work could be carried out.
